ABAP_SOURCE_CODE
ABAP_EXEC

ABAP_DESCRIPTION
The counter_ten class is derived from counter and redefines the increment method. In counter , the visibility of the attribute count must be changed from PRIVATE to PROTECTED . In the redefined method, the nested method with the pseudo reference super- is called. The redefined method specializes the inherited method.
An object of the subclass is created, to which a reference variable of the superclass type points. During the execution of the increment
method, the redefined method of the subclass is executed using the superclass reference.
